My problem is that with i.cluster I can not create the "spectral signature" which then must be used in the second module. Why?
The signature file is stored in the current mapset. When you use GRASS through QGIS, a temporary location and mapset is created and again deleted once the GRASS process has finished. That means the signature file is created, but again deleted when QGIS deletes the temporary location/mapset. The solution is to use GRASS directly.
